Abstract
The utility model discloses a hexagon check nut which comprises a hexagon nut body. First inner threads are arranged on the hexagon nut body, a cylinder integrated with the hexagon nut body is arranged on the hexagon nut body, second inner threads consistent with the first inner threads are arranged on the cylinder, a transverse groove with a 'V'-shaped structure is arranged on the outer wall of the hexagon nut body, and the depth of the transverse groove reaches the position of the center line of the first inner threads. The hexagon check nut resolves the problem in the prior art that the nut is easy to fall, high in cost, low in connection strength and poor in fastening performance in the using process.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly hexagon check nut.
Background technique
Nut usually plays the effect that is connected fastening component with bolt, screw fit use, has internal thread in its screw of general hexagon nut and is used with bolt, is widely used in the mechanical connection field.When nut was connected with bolt, the screw thread place left the gap, can not effectively screw; Cause nut to use the back owing to the reason of extraneous vibration gets loose for a long time, therefore fastening effect is poor, in the prior art; Nut and bolt adopt the mode that improves pretightening force usually, as add elastic washer, nylon etc. in order to prevent the loosening of nut; Though the effect of the nut anti-looseness that this method can play, in actual application, the effect of carrying out cloudy pine through pad upper spring packing ring is not very desirable; Time has been grown, and the phenomenon that gets loose is still relatively more serious.
Summary of the invention
The purpose of the utility model is to provide for the deficiency that solves above-mentioned existing technology that a kind of join strength is high, tightness is good, can effectively prevent the lock nut that gets loose.
To achieve these goals; The hexagon check nut that the utility model designed comprises the hexagon nut body, on the hexagon nut body, is provided with first internal thread; On the hexagon nut body, be provided with cylindrical body integrated with it; And cylindrical body is provided with second internal thread consistent with the diameter of first internal thread, on the outer wall of hexagon nut body, offers the transverse groove of " V " type structure, the position of center line of the transverse groove degree of depth to the first internal thread.
In use, when nut cooperate with bolt tighten after, impact the position of this transverse groove one side with external force; Make transverse groove under the effect of external force, produce distortion, reduced width drives opening slot simultaneously and under the effect of coupling mechanism force, produces the distortion reduced width; Drive internal thread simultaneously and produce distortion and be clamped in tightly on the screw thread of bolt, eliminated the crack of asking of screw thread between nut and the bolt, reach the purpose of locking anticreep; Improved the join strength between the utility model and the bolt; Owing on the hexagon nut body, be provided with cylindrical body, increase the area of contact between the utility model and the bolt simultaneously, made tightness better; Need not all be set as simultaneously the shape of hexagon nut body, therefore under the situation that stressed area of contact increases, practice thrift cost simultaneously.
The hexagon check nut that the utility model obtains, compared with prior art: have join strength height, tightness good, can effectively prevent to get loose and the advantage of under the situation that stressed area of contact increases, having practiced thrift cost simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment:
In Fig. 1; Hexagon check nut hexagon nut body 1; On hexagon nut body 1, be provided with first internal thread; On hexagon nut body 1, be provided with cylindrical body 2 integrated, and cylindrical body 2 is provided with second internal thread 3 consistent with the diameter of first internal thread, on the outer wall of hexagon nut body 1, offers the transverse groove 4 of " V " type structure with it; The position of center line of transverse groove 4 degree of depth to the first internal threads, the transverse groove 4 of said " V " type structure can be selected one or a plurality of according to the requirement in the specific embodiment.
In use, when nut cooperate with bolt tighten after, impact the position of this transverse groove one side with external force; Make transverse groove under the effect of external force, produce distortion, reduced width drives opening slot simultaneously and under the effect of coupling mechanism force, produces the distortion reduced width; Drive internal thread simultaneously and produce distortion and be clamped in tightly on the screw thread of bolt, eliminated the crack of asking of screw thread between nut and the bolt, reach the purpose of locking anticreep; Improved the join strength between the utility model and the bolt; Owing on the hexagon nut body, be provided with cylindrical body, increase the area of contact between the utility model and the bolt simultaneously, made tightness better; Need not all be set as simultaneously the shape of hexagon nut body, therefore under the situation that stressed area of contact increases, practice thrift cost simultaneously.
